Subject: About search algorithms and heuristics

  I'm curious about what search algorithms and heuristics do commercial and
amateur programs use, for example, null move vs no null move, PVS vs MTD(f) and
so on.
  In Averno, I use PVS and AS, and haven't tried null move cause I'm a little
afraid of losing precision in short tactics, though I see most programs use null
move.
  Junior is said not use null move. Do any other of you guys or commecial
programmers not use null move? If so, what are your reasons?
  Who of you have tried MTD(f)? Why did you keep/discard it?
  What other algorithms/heuristics are you using or did you discard?

  Thanks in advance.
